13x6 - Food Network Star

It's halfway through the competition, so it's time for midterms! Each of the remaining seven finalists must make their best potato dish and overcome the one thing in the competition that has been holding them back. Then it's time to celebrate summer with Tiffani Thiessen, who helps Giada De Laurentiis and Bobby Flay judge the finalists' efforts as they each host a summer social gathering for a crowd of people in a park.
